Re: [Chicken-users] sxml and more

[Nathaniel Rudavsky-Brody]

Thanks Peter and Jim, that makes a lot of sense. Even if they never get homogenized, I'm glad the sxml tools exist, and the Chicken division definitely helps.

I guess my question boils down to "what am I missing" – do the low-level functions only serve for writing the top-level ones, or do they have uses of their own, which I can't imagine because I'm coming to XML-processing with an XSLT mindset.

I'll start digging around the Sourceforge list archives...

I've got a couple of blog posts on SXML and namespaces, if you haven't already seen them:

http://3e8.org/blog/2010/08/01/default-namespaces-in-sxml/

but these are higher-level and so perhaps not useful to you.

There's definitely very little documentation and only marginally more code examples.  Most of this I reverse engineered from docs I pieced together and the original code itself.  Peter did a great job at adding a lot of documentation, for example to the sxpath low-level functions, but there are still large gaps.  There's also bugs and missing functionality.  And as noted, it's a grab-bag of parts which don't necessarily work together, or provide an 80% solution.  Case in point, the lack of namespace support in sxml-modify.

If you have specific questions you could try asking here, or on the Sourceforge list.  I haven't used sxml-modify myself.  Which low-level tools did you want to learn about?

Hello,

Since this is my first post, let me say how happy I've been since I discovered Chicken: thanks everyone for creating such a well-thought-out environment.

I've got a general question about the sxml tools. I've been using the top-level functions for a while now, for tasks I could do in XSLT, but prefer doing in Scheme. I've always found the lower-level interface(s) a bit intimidating. 

But recently I got stuck on the lack of namespaces in sxml-modify, and started wondering if it would be possible to rewrite it, and then... well more generally, whether it's worth learning how to use the low-level tools, and what I could do with them. Or are pre-post-order and sxpath and sxml-path as good as it gets, for an average user like me? When I search around the web, I can't seem to find examples of more advanced uses of the tools (or at least, well-documented ones...).

Many thanks for your thoughts,

Nathaniel
